Bender UK is an expert in the field of electrical safety, and for more than a decade has delivered a range of innovative solutions for electric and hybrid vehicles and charging infrastructure.


For the design of electric charge systems Bender supplies the new RCMB121 AC/DC sensitive residual current monitoring solution to enable charging station manufacturers to cost-effectively comply with the latest BS7671 EV charging regulations.

If DC fault current within a charge station is greater than 6mA, it could change the characteristics of a Type A RCD due to its core saturation, resulting in the Type A failing to trip and failing to detect the DC fault. As a result, the 18th Edition BS7671 Section 722.531.2.101 states that protective measures against DC fault current must be designed into all new electric vehicle charge stations.

The 6mA DC sensor RCMB121 from Bender UK works in conjunction with a Type A RCD, offering a significantly cheaper alternative to Type B RCD for AC charge stations.


For electric vehicle charging Bender offers a Mode-3 electric vehicle charge station components as a modular kit, allowing manufacturers to create their own charge station without having the necessary technical expertise.

Our electrical components offer a proven, cost- effective, low risk solution for EV charge station development. This market-ready modular suite of products provides all the internal components required to develop a charge station.

Reducing cost and development time, the modular kit offers a fast route to market for charge station manufacturers and developers.


The main component of an electric vehicle charge station, our intelligent charge controller CC612 has been adopted and proven in use internationally by major charge station manufacturers.

The CC612 is proven charge control technology used in third-party charge stations and the Bender modular kit.

Designed to monitor the integrity of the charge system, the unit supports OCPP 1.5/1.6 incorporating a power supply, contactor, charging socket, IEC 61851 Mode-3 commercial charge controller and remote access for software updates and monitoring.


Bender has developed customised on board insulation monitoring devices for vehicles to monitor the insulation of the AC motor and DC side of electrical drive and connected battery systems.

Our IR155xx range is patented measurement technology that enables continuous measurement of insulation resistance between 0 and 10MΩ. Variants of the device are proven in Formula 1, E, London’s hybrid ‘Boris Buses’, commercial vehicles and OEM applications.

Bender UK has a total capability in e-mobility, supplying pioneering solutions for electric vehicle development and on-board safety, reducing the likelihood of vehicle failure and eliminating any risks to the end-user.

Bender UK is a subsidiary of Bender GmbH – a global, independent company established in the 1940s by Walter Bender. The family owned company has 80 offices worldwide, with headquarters and state of the art production facilities in Grunberg, Germany.

Bender is involved in the innovative design and manufacture of quality electrical safety solutions, serving a range of market sectors delivering solutions which identify electrical faults before they become critical. Key markets include defence, oil, gas and mining, manufacturing, data centres, electric vehicles, rail and healthcare.

Cumbrian based Bender UK is responsible for sales, project management, installation and through-life technical support of Bender products in the UK and Ireland.  The Bender UK team work with leading OEMs, consultants, engineers and end-users to deliver solutions which monitor, forewarn and locate developing insulation failure in complex electrical systems.

Bender UK works in key market sectors, to prevent loss of power and shut-down:

Industrial: Residual current monitoring and power quality management devices monitor electrical networks, plant, and buildings to ensure that they are electrically safe. Bender systems provide a continuous health check on electrical systems delivering far-reaching and cost-effective benefits by predicting when and where issues will occur, tracking power usage to identify potential energy savings.

E-Mobility: Bender is a world leader in the application of safety solutions for charge stations and operating systems for hybrid and electric vehicles.  Collaborating with major manufacturers on passenger, transport and commercial vehicle projects, Bender supplies compliant charge station technologies and insulation monitoring for new generation vehicles.

Rail: An approved supplier to Network Rail, Bender UK technology monitors and protects trackside power supplies and signal systems across the UK, identifying and locating electrical faults, anticipating failure to enable predictive and preventive maintenance, keeping rail networks moving.

Oil, Gas and subsea: Effective management of offshore, on-shore and oil and gas infrastructure is facilitated by Bender line insulation monitoring equipment to prevent downtime and loss of production. Bender also collaborates with OEMs on bespoke offshore and sub-sea applications, utilising certified engineers to conduct fault finding analysis, health surveys and commissioning.

Defence: Complex systems on board Royal Navy surface ships and Astute-class submarines are protected by Bender technology to identify and locate earth faults and help prevent electrical failure.

Healthcare: In the UK and Ireland, Bender is market leader in turnkey healthcare solutions, delivering critical care power systems to protect staff and patients from loss of power in hospitals.   Bender also supplies clinical equipment including high performance Merivaara LED surgical lighting and operating tables, infection-reducing touch screen control panels, and clinical services pendants, backed up by 24/7 service, call-out and technical support support to over 400 hospitals.

From off-the-shelf products, to highly customised systems Bender is a supplier of choice to deliver world-class services for critical infrastructure applications.
